I have recently clocked my i7 4790k to 4.4ghz and ran some tests and at 100% load all cores are averaging about 50 degrees Celsius, however, what came across my mind was that if i was doing this will it significantly lower the lifespan of my cpu. I'm currently cooling it with a corsair h110i gt and i am wanting to use this cpu for about 7-10 years, how long will my cpu last considering it is kept in a safe environment and all im doing is casual work and playing games
Does overclocking significantly reduce the life of a cpu?

If that's all you're doing you wont need a 4.4GHz overclock. What tasks does your CPU bottleneck things at the moment? You only really need to OC if you have a reason to, like GPU bottleneck or increased video encoding speeds, but yes it does theoretically shorten the lifespan of the CPU, but by how long is debatable, and most people will tell you they havent had any problems with sensible, properly done OC's. The fact your CPU stays at 50c at full load is a good sign, but thats because the cooler is good. Your actual chip may experience higher variations in temps in millisecond terms, and if you can avoid it, dont overclock is the simple answer.
Overclockers have a general disdain for their hardware and usually accept there may be sacrifices by pushing the CPU to its limits either for fun or sport.

Read the disclaimers on overclocking your CPU, motherboard, and RAM. Realize that when you are overclocking you are running outside the guaranteed specifications of the products. And over time as things heat and expand and cool and contract and heat sinks get dirty and fans lose capacity things are constantly going downhill but very slowly. The problem is that you won't know you're having a problem until it is already critical. Any damage done will be permanent so you won't be able to correct by going back to the normal clock speeds.
If you don't have a specific need for overclocking that you are willing to risk permanent damage to attain, then don't overclock.
IMO, you'll be very lucky to get 10 years out of a non-overclocked system.

A "K" is designed to be overclocked.
Intel can not guarantee how high because chips are different.
The key to longevity will be to keep the vcore voltage under control.
Probably 1.3v is as high as you want to go.
CPU-Z will tell you.
Best to use ram at 1.5v also and not 1.65v overclocked ram.
The thermal limit for the cpu is around 100c.
You mostly run out of safe vcore before temperatures with a good cooler and case exceed 75c. or so at peak.

No, they are not designed differently. There's a process called "binning" that's performed during the testing phase. Those chips that perform exceptionally well are but in a different bin and used in the K series and sold at a higher price. It's a way to maximize profits.
Those that pass the tests as stable but not exceptionally so are binned for the non-K products. And their circuitry is change by "fusing" to disable overclocking. That means certain connections are intentionally overloaded to destroy a part of the circuit that was intentionally put there to act as a fuse.
And some that fail their target testing but qualify for a lower level of stability can be used for down rated CPU, i.e. same chip but at a lower guaranteed clock rate. Again, it's a way to maximize profits. If it will perform at a lower clock speed and remain stable it's better to sell it with the lower clock speed than throw it away.
But all of the circuits that come from the same silicone platter have the same design and production process.
